Abstract: 22,356. Fell, J. C., [Wyckoff, Seamans, & Benedict]. Sept. 29. Type-writers.-Relates more particularly to the paper carriages and shift mechanism of Remington machines. Fig. 4 shows a vertical section through the carriage &c. On the framing are lugs 9 carrying a grooved rail 10, on which the grooved bar 13 of the carriage runs. In the grooves of the bars 10, 13 are two pairs of rollers pivoted on a carrier of bent sheet metal. The axes of the rollers of each pair are at rightangles to each other. Projecting rearwards from the carriage are three arms 34 carrying a bar 35 which runs against a roller 36 in a bracket 37. An arm 22 prevents the bar 35 from descending when the platen carrier is turned up. The platen frame 60 is pivoted at 59 in bars 42 mounted to slide in the carriage to shift the platen to upper and lower case positions. Each bar 42 runs on two balls 54, 44 which work in grooves in the bars and in the carriage. The bars 42 are suitably guided, but are held in engagement with the balls by the weight of the platen and its frame. In the platen frame 60 are screws 64 bearing against downward projections 63 of the arms 42. By means of the screws 64 the position of the platen may be adjusted. The front of the platen frame is provided with rollers 69 engaging the shift bar 67. To partially counterbalance the weight of the platen and its frame 60, springs are applied to the pivots 59. Both ends of the platen carrier are caused to move together by arms 70 engaging the bars 42. The arms 70 are on a shaft in brackets 72 forming part of the carriage frame. The shifting movement of the platen carrier is limited by stops on the carriage. The shift bar 67 is operated by shift-key mechanism of known construction, but in order to prevent the platen from being forced too hard against the stops, the connection to the shift key is made through a spring arrangement of special form. The feed-rack 135 is carried by arms 136 pivoted on the carriage. The rack may be lifted to release it from the wheel 140 when the platen frame is in either its normal or lifted position by means of release keys &c. arranged on the platen frame and carriage. The platen is mounted so as to be readily removable from its frame 60. At one end the platen shaft is in a plain open slot in the frame 60, and at the other end in a keyhole slot. On the shaft is a collar which fits the enlarged part of the keyhole slot, and is held therein by an arm on the collar engaging the end of the frame 60. By moving the shaft and platen endways, the collar is disengaged and the platen may be lifted out of the frame. Three scales 156, 157, and 159 are provided on the carriage. By the scales 157 and 159 the carriage may be brought to any desired position while the platen is lifted. The scale 157 is preferably mounted on the paper guide 161, through openings in which the pressure rollers 164 engage the platen. The rollers 164 are in spring- pressed arms, which may be moved by means of wings on a shaft 167 to lift the rollers from the platen. A pivot for the shift-key lever is provided, such that the lever may be engaged with or removed from the pivot shaft. The end of the key lever is so cut or formed that the eye or part engaging the pivot shaft is open at the rear and is elastic so that it may be pushed on to or pulled off the pivot shaft.
